Our military adopting the Grendel?

If you strengthen the bolt, the barrel extension becomes the issue. Strengthen the barrel extension, and another point becomes the weak point. Keep that up, and eventually you end up with a 15-20 pound Carbine. The .30 RAR is a hunting rifle, with inferior ballistics. Bigger bolt, but very limited real options as far as bullet options that work from mags.

Bolts are exspendables, and when a bolt goes, there is really very little damage to the rifle. Maybe a mag is damaged, but other than that, no real damage, generally. It acts like a circuit breaker in an electrical system, and prevents further damage.

I know LRRPF52 thinks that improving or increasing bolt size might be helpful, and I certainly recognize his significantly higher level of experience than my own, but it seems like we might be asking the wrong question when it relates to the AR. The AR works, we actually have very few bolt failures at this stage, and those we have are not catastrophic. I'm not sure that is the right move.

Bill you may be correct in your statement I was really just think out loud but to clearify

Actually I not advocating the .30 RAR just the design of the Bolt, the Extentsion, and the mod to the carrier this would (my opinion without any data or supporting docs) provide a basis for the brass of the cartridge to be the weak link versus the Bolt of the AR platform. Which STILL provides the jamming issue that many have brought up. My short easy answer is use a three lug bolt system do away with the current multi lug setup. After all I just attempting fix the massive jamming issue even though 18 months in Iraq SEVERAL mission clearing IEDs, doing route clearance in sand storms in a asture enviroment my weapon never jammed or misfed. Not to mention that year I spent in the Saudi /Iraqi Desert in the 90s and on G day nooooo issues.
which begs the question why did I clean that thing after every mission and run her dry until ready to go, then light lube critical spots???? ohhhhh yeah I remember first sandstorm in 90 after heavy lubing left the action filled with CLP mud that's why. (and I will not carry a Colt marked weapon period.. any other manufactuer is good to go I consider a Colt badd ju ju personal opinion)
